Really awesome. Time - Growth metaphor is really helpful.

I like that way you teach Mr Woo, please keep making these great video where you explain why these concepts work in maths and the real world.

I didn’t know this law beforehand. Understood the proof and seemed natural, but if I were given just a formula it looks so weird for some reason. Glad to have found this channel

My intuition of this was scales... basically, if you imagine, say a log scale y axis for log10 and log2, you need to scale one to the other at all points including 10, 100 to 5, 25. The ration of the scaling will always be log_c a as the scales have to be increased or decreased exponentially as well, and thus the original log value on the y gets 'scaled' moving from one to the other.

Hi Sir
I would very much appreciate it if you could explain the change of base law in terms of the time-growth metaphor.
Kind regards

Hmm.. But why do we have to change other number to 10 or e base?
what is the point of changing the base number?
